The only certainty in water resources management is that practitioners are required to make sane pragmatic operational and planning decisions under highly variable climatic conditions with a paucity of observed hydrological data. In addition to the many research questions raised in response to this need, there is a strong requirement to identify means by which research results and tools can be matured and migrated into hydrological practice in a way that benefits a broad spectrum of water users. With the increased availability of remote sensing data to complement in-situ observations, and readily available computing technologies, this is an exciting time to model and observe hydrological processes at new time and space scales.
